I typically don't keep much more than a couple grand in the house at once, and there is literally a gun stashed in every room of my house, bathrooms included. It would be tough to get the drop on me, and you are risking a lot coming to take it, for relatively not a lot of money.

If someone broke in while I wasn't there, they'd never find any cash anyway. Most of my guns are in a safe, I guess you could steal my TVs? The only guns lying around are the ones I stashed throughout the house, (handguns), an AK and a mossberg pump.
